Grande performed Sunday as part of the "One Love Manchester" benefit concert, where proceeds were donated to the Manchester Emergency Fund to assist victims and their families.

Salman Abedi, 22, a Briton of Libyan descent, was identified as the suicide bomber in the deadly attack, which occurred as Grande's concert was letting out. A total of 21 people were arrested in connection with the bombing and 12 had been released without charge.
